EVAPORATOR COIL FAN DISCHARGE / TXV (THERMOSTATIC EXPANSION VALVE)
1. Evaporator Coil Fan Discharge
• When main power switch is turned on, refrigeration assembly will energize (see FRONT GRILLE
REMOVAL / CONDENSER PACKAGE / OVERFLOW PAN / MAIN POWER SWITCH section for
startup specifics).
• Evaporator coil fans should turn on. From inside of the case, check for discharge air from front baffle to
confirm that the fans are functioning properly.
• When the case is in a start up mode or has been idle for a long period of time, the unit will require 75
minutes of run time to pull-down temperature.
• See below illustration.
2. TXV (Thermostatic Expansion Valve)
• TXV is under TXV access panel.
• Decking must be removed for access.
• TXV cover must also be removed for access (remove two thumb screws).
